Meshy models can be exported to almost every popular 3D printing slicer, but the right file format and workflow depend on which slicer you use. This guide breaks down the best export settings for Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, and Creality Print, so your model imports cleanly and prints the way it looked in Meshy.
Choosing a File Format
STL — geometry only, no color or texture. Works everywhere, but you lose all color data.
3MF — preserves color and multi-part information. Best for Bambu Studio, OrcaSlicer, and PrusaSlicer, which all read 3MF color data natively.
OBJ — carries textures/materials but is less consistently supported for slicer color import than 3MF.
If your model is a single color or you only need the shape, STL is simplest. If you generated a multi-color print in Meshy, always export as 3MF to keep the color assignments intact.
Slicer-by-Slicer Guide
Bambu Studio / OrcaSlicer
Both are built on the same underlying engine, so the workflow is identical. Export as 3MF for multi-color models, or use the Bambu Studio plugin to send models directly from Meshy without a manual export step. Use the Color Painting tool in Bambu Studio to fine-tune filament assignments after import.
PrusaSlicer
Import 3MF for color-preserving prints, or STL for single-material models. PrusaSlicer's multi-material (MMU) workflow reads 3MF color regions the same way Bambu Studio does.
Ultimaker Cura
Cura's 3MF color support is less reliable across versions — for predictable results, export as STL and manually assign extruders/colors per model or per mesh in Cura.
Creality Print
Creality Print supports 3MF for multi-color AMS-style printers and STL for single-color prints. Use the Creality Print plugin to send models directly, avoiding a manual file transfer.
Scale, Repair, and Prep
Check your model's real-world dimensions in Meshy before export — resize it there rather than in the slicer to avoid distorting proportions.
Look for a closed, watertight mesh with no floating parts before printing; open a model in Blender or Meshmixer first if you see holes or stray geometry.
Keep a flat, stable base for bed adhesion, and reduce steep overhangs if your printer needs supports.
FAQ
1. Which format should I use if I only care about shape, not color?
Export as STL. It's the most universally supported format and keeps file size small.
2. My multi-color model lost its colors after importing into my slicer. What happened?
You likely exported as STL instead of 3MF. STL does not carry color data — re-export as 3MF and reimport.
3. Do I need a plugin, or can I always export manually?
Plugins are optional conveniences — they skip the manual export/import step for Bambu Studio, OrcaSlicer, and Creality Print. Manual 3MF/STL export works with any slicer.
4. My model prints at the wrong size. Where do I fix that?
Resize the model inside Meshy before exporting so the scale is baked into the file, rather than relying on the slicer's scale tool.
